How do I create an installer for a java Application using exe4j?

Question

When I create an installer using exe4j , I'm getting these errors:

java.lang.UnsupportedClassVersionError: credit/home : Unsupported major.minor version 52.0
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(Unknown Source)
at java.security.SecureClassLoader.defineClass(Unknown Source)

at java.lang.ClassLoader.loadClass(Unknown Source)
at com.exe4j.runtime.LauncherEngine.launch(Unknown Source)
at com.exe4j.runtime.WinLauncher.main(Unknown Source)

What am I suppose to do to fix these errors? Is this my Netbeans Project Error?

右键单击您的项目，转到属性，然后查看Java编译器版本和Java构建路径是否都使用相同的Java版本。
